Geomorphic Channel Design and Analysis Using HECRAS Hydraulic Design Functions

Darshan Mehta, Sahita Waikhom, Dr. S M Yadav

Abstract :

This paper presents a preliminary design for physical enhancement of the reach of the Tapi River located near the confluence of Arabian Sea and the Tapi River in Surat City, Gujarat. In this paper designing of stable channel has been done using the Copeland method which has been included in the Army Corps of Engineers Hydraulic Engineering Center River Analysis System (HEC–RAS). This method requires the bottom width, depth, and side slopes of a representative cross–section from a stable, upstream reach as input. A flood in river Tapi affects Surat city and surrounding regions.
